Bad news. I just went through about a hundred pictures of hatches and guess what? None of them have eyebolts and rings. All that work… I thought I had seen a hatch cover with them once and thought they looked pretty cool, but I must have been dreaming. All is not lost, though. Now I know how to make them using two eye pins. These will be covered by a deck or life boats anyway. No loss. At this point I’m not envisioning adding them to the three hatches that will show unless I find some evidence they actually existed on real ships of this period.
